The strands aregathered by passing through a die and covered in reverse wrappings. by passing through revolving heads mounted with paper spools, andthrough dies to compact the paper winding. The cable is drawn bythe take-up wheel, which is conical on the face and draws by severalfrictional windings. 393. CHLORIDE ACCUMULATOR or storage battery. Thealternate perforated plates are filled with peroxide of lead and spongy lead. The principal action when the cell ischarged is the formation of lead peroxide onthe positive plate and spongy lead on thenegative. When the cell is discharging, thelead peroxide gradually changes to lead sul-phate and the metallic lead on the negativeplate also changes to lead sulphate. c^ b, recesses in the lead plates for receivingthe spongy lead. Sulphuric acid i part andwater 8 parts for filling the cell. 165
